G2 heading hold question
 

When using the heading hold gyro I fly with the heading hold option "always" on. Does anybody know how to configure the gyro so that one of the other switches can disable this feature in flight, and if so which switch? I know that you can disable the heading hold feature in either throttle mode or regular idle up mode prior to flight, but it would be nice to be able to change this during flight. Also, what switch number do we use when we are using idle up 2 mode?
Thanks,
